Static Single Assignment (SSA) form has shown its usefulness for powerful code optimization techniques, such as constant propagation, of sequential programs. We introduce a new Parallel Static Single Assignment (PSSA) form and the transformation algorithm for the explicitly parallel programs with interleaving semantics and post-wait synchronization. The parallel construct considered in this pap...

Static Single Assignment (SSA) form has shown its usefulness for powerful code optimization techniques such as constant propagation in sequential programs. We introduce the Concurrent Static Single Assignment (CSSA) form and the transformation algorithm for explicitly parallel programs with interleaving semantics and post-wait synchronization. The parallel construct considered in this paper is ...

In this paper we study the properties of the chaotic wave fields generated in the frame of the Kundu-Eckhaus equation (KEE). Modulation instability results in a chaotic wave field which exhibits small-scale filaments with a free propagation constant, k. The average velocity of the filaments is approximately given by the average group velocity calculated from the dispersion relation for the plan...

The identification process of gas flavor is conducted by using the output of gas sensor system to recognize a variety of gas flavor. The identification and analysis process of this system is processed by using an artificial neural network approaches those are back propagation and Kohonen method. According of the experiment’s result, the best parameter for back propagation network is the momentu...

We present numerical simulations for the propagation of surface plasmon polaritons (SPPs) in a dielectric-metal-dielectric waveguide using COMSOL multiphysics software. We show that the use of an active dielectric with gain that compensates metal absorption losses enhances substantially plasmon propagation. Furthermore, the introduction of the active material induces, for a specific gain value,...

We study a lattice model for mode III crack propagation in brittle materials in a stripe geometry at constant applied stretching. Stiffening of the material at large deformation produces supersonic crack propagation. For large stretching the propagation is guided by well-developed soliton waves. For low stretching, the crack-tip velocity has a universal dependence on stretching that can be obta...
